标题: 【求助】less作为名词，OG-11 第77题 [打印本页] 作者: pipiyu12 时间: 2008-8-18 22:08 标题: 【求助】less作为名词，OG-11 第77题 77.Even though the direct costs of malpractice disputes amounts to a sum lower than 1 percent of the $541 billion the nation spent on health care last year, doctors say fear of law suits plays a major role in health-care inflation. A) amounts to a sum lower than B) amounts to less C) amounted to less D) amounted to lower E) amounted to a lower sum OG解释：amount为动词，to为介词，less为名词可以作为to的宾语，而lower为adj不可以做宾语。amount与sum重复。
请问：如果名词less作为to的宾语，那么在宾语less之后的“1 percent of the $541 billion”作为句子的什么成分呢？ 谢谢
